CASH-REGISTER.

T 0 all whom it may concern:

Be it known that I, CHARLES A. Lonn- GREN, a citizen of the UnitedStates, residing at Dayton, in the county of Montgomery and State ofOhio, have invented certain new and useful Improvements inCash-Registers, of which I declare the following to be a full, clear,and exact description.

This invention relates to cash registers and has for its object toprovide a machine especially for use in canceling so called bundletickets or delivery slips.

In many commercial houses, for example, a sale slip is made out induplicate, one copy being filed and the other copy being given to thecustomer who thereupon takes the purchase away with him or her. Thissystem in practice is fairly satisfactory in cases where the customerdoes not desire the bundle delivered by the store but in cases where adelivery is to be made as by wagon, opportunity is given to the clerksto defraud the proprietor. This duplicate slip system is also used inconnection with a well known type of cash register in which the machineprints the amount of the sale in two places on a slip which is thensevered into two parts, one of which is retained in the machine as avoucher, the other being ejected and serving as a receipt. In the use ofsuch nachines in connection with a sale for immediate delivery theamount received must be added in on the machine in order to print on theslip, without which the bundle will not be wrapped. In the case of asale with future delivery an operation of the machine is made and thesale slip attached to the bundle which is then taken to a room to bewrapped, and in such cases some means of authorizing the wrapping andsending out of the package must be provided.

My invention aims to provide means for authorizing such wrapping anddelivery and to this end I employ a delivery slip or bundle ticketlonger than the usual sale slip, which is adapted to have printedthereon such matter as the word Paid and the date or other desiredmatter. The portion of the slip bearing this matter may be de tached andpasted or otherwise attached to the bundle, and will be understood asauthorizing its delivery.

In particular this invention aims to im- Specification of LettersPatent.

prove the machine shown in application bearing Serial. Number 160,t16,filed June 6, 1903, by Thomas Carroll. The machine shown in saidapplication is designed to make two printing impressions on a sale slip,one part. of the slip being retained in the machine after the impressionis made and the other part being taken from the machine after printing.

For use in connection with future delivery sales I provide a longerbundle ticket or delivery slip than the usual sale slip and means areprovided for marking this slip with a record of any desired matter 6. g.the word Paid and the date. The machine includes an extra printingdevice so located as not to operate on the usual sale slip as such slipis not long enough to reach the extra printing device but when a longerbundle ticket is inserted in the machine the above stated additionalimpression will be made.

\Vith these and incidental objects in view, the invention consists incertain novel features of construction and combinations of parts, theessential elements of which are set forth in appended claims and apreferred form of embodiment of which is hereinafter specificallydescribed with reference to the drawings which accompany and form partof this specification.

Of said drawings: Figure 1 represents a vertical transverse sectionthrough the machine and cabinet showing the operating cam and the mainprinting table. Fig. 2 represents a vertical transverse section throughthe machine and cabinet showing the vertical shaft and its operatingmecha nism. Figs. 2 2 and 2 are detail views of the auxiliary printingdevice and Fig. 3 represents a rear view of part of the machine with thecabinet partly broken away.

The main revolution shaft 10 is rotated by any suitable drivingmechanism and receives one complete revolution at each operation of themachine in the direction of the arrow in Fig. 1.

Fast to ,the shaft 10 is a disk 11 in which is formed a cam groove 12adapted to engage an anti-friction roller 13 mounted on a reciprocatinglever 14. The lever 14 is so formed as to straddle the shaft 10 and hasan upward and rearwardly extending arm 15. Extending laterally from thearm is a rack 16 which engages a pinion 17 mounted on a vertical shaft18 which is given a partial revolution at each operation of the machineas will be explained later on. The other end of the lever 14 is pivotedto an arm 19 which is in turn pivoted to the frame work of the machine.

As seen in Fig. 3 the hub of the pinion 17 is provided with a pin 20which extends into a groove 21 in the shaft 18. This makes it possiblefor the shaft to receive a reciprocatory movement in addition to andwithoutinterfering with its revoluble movement. This reciprocatorymovement is produced by the following mechanism: Fast to the shaft 10 isa disk 25 in which is formed a cam groove 20 adapted to operate upon ananti-friction roller 27 mounted on an arm extending upwardly from alever 28. The lever 28 is pivoted on the frame work of the machine at 29and has at its other end a pin 30 adapted to engage bet-ween two disks31 fast to the lower end of the shaft 18. The above mentioned disks 11and 25 and others of the same kind will hereafter be men tioned as boxcams. The relative timing of these two movements of the shaft 18 will bedescribed later on.

Removably secured to the upper end of the shaft 18 is a frame 35 whichcontains the auxiliary printing wheels 36. These printing wheels 36 havesuitable numbers and characters for printing the date equallydistributed around their periphery and are held in printing alinement bysuitable spring pressed alining plungers 37 engaging toothed aliningwheels 38 of which there is one fastened to each printing wheel.

The hub 39 of the frame 35 is held in position against a collar 10(which is secured to the shaft 18) by a thumb screw 41 and is preventedfrom turning on said shaft by a tongue and groove 42 between said hub 39and the collar stO. In the forward end of the frame 35 is mounted aspring pressed. plunger 43 which has a flange M- at its upper end tolimit its movement in one direction. In the normal position of the frame35 (see Fig. 2) the plunger 13 rests on the cabinet of the machine withits spring contracted but as soon as the frame is raised the plungerwill assume a position like that shown in Fig. 3. Fastened to the underside of the frame 35 is a plate 45 having the word Paid engraved thereonso as to print said word in connection with the date.

In a recess in the cabinet there is an inking pad 46 upon which theauxiliary priut ing wheels 36 and plate 45 rest when the frame is innormal position. This supplies the wheels and plate with ink.

The impression platen 50 is pivoted at 51 to the framework of themachine and has an impression block 52 made of rubber or other suitablematerial. A spring normally tends to draw the platen down but isnormally prevented from doing so, (see Fig. 3) by a spring pressed pawl53 which ongages a laterally projecting pin 54lmounted on the platen 50.This pawl 53 is pivoted at 56 and has a foot 57 which is operated uponby a downwardly projecting foot 58 of a tripping pawl 59 to trip thepawl 53 from the pin 54. This will allow the platen 50 to be drawndownwardly by the spring and will prevent any printing as the impressionblock will then be below the printing line. The pawl is provided with apin 60 which contacts with the framework of the machine to limit itsdownward movement. A spring (31 is coiled around the hub of the pawl andtends to force said pawl into locking engagement with the pin 5 of theimpression platen 50. The pawl 55) is operated upon by the plunger 4-3in the following manner.

If a delivery slip (which is longer than the regular sale slip) isinserted into the machine it will extend over the impression block 52and also over a. hole 2 in the cabinet of the machine. When the machineis operated the shaft 18 will first be lifted to raise the auxiliaryprinting mechanism from the inking pad is. The shaft 18 will now berotated to bring said printing mechanism into the position shown in lig. 3 and will then be lowered to print on the delivery slip. The slipbeing in position will receive the printed impression because the paperover the hole prevents the plunger 43 from entering said hole andoperating the pawl 59 to trip the pawl 53 from engagement with the pinAfter the printing is done the shaft 18 is again raised and then rotatedback to normal position, the last movement being to lower the auxiliaryprinting mechanism so the type wheels 36 and the plate 37 will rest onthe inking pad 1 The spring of the plunger is light enough to allow theplunger 43 to operate without breaking through the paper.

If there is only a regular sale slip in the machine the following willresult: The sale slip is not long enough to extend over the impressionblock 52 and the hole (32 therefore the plunger .43 will (upon theoperation of the maehine)operate the pawl 59 to trip the pawl 53 fromengagement with the pin thereby allowing the impression platen 50 to bedrawn downward by its spring 55 until the pin 5 1-v strikes theframework of the machine. It will be readily un derstood that in thisposition the auxiliary printing will be rendered ineffective.

The impression platen 50 is restored to its normal position by thefollowing mechanism. Mounted loosely on a. shaft is a pawl 71 having adownwardly extending arm 72 and an upwardly extending shoulder 73. Astop pin 74 limits the movement of the pawl 71 in one direction. Asuitable spring (not shown) normally tends to draw the pawl 71 againstthe pin 74. Mounted on the box cam are two pins 76 and 77 which strikethe forward side of the arm 72 of the pawl 71 to lift the shoulder 73upward against the under side of the impression lever 50 to restore thesame to normal position. The pin 76 first acts on the arm 72 to restorethe platen 50 if it has been accidentally or otherwise tripped and thepin 77 acts on said arm to restore said platen after the printingoperation is completed. The main printing wheels are set to print thedifferent amounts by mechanism described and shown in the abovementioned pending application. The main printing platen or table 91 hasa downwardly extending arm 92 provided with an anti-friction roller 93which is operated upon by a cam groove 94 of the box cam 80 to vibratethe table 91 up and down twice to make two impressions on the paperstrip. Between these two impressions the paper slip is fed forward bythe following mechanism. A cam groove 95 is formed in the box cam 25 andacts upon an anti-friction roller 96 mounted upon one end of a bellcrank lever 97 pivoted on a stub shaft 98 to reciprocate a rack bar 99which meshes with a pinion 100 mounted upon one end of a shaft 101. Theshaft 101 is mounted in the table 91 and has mounted thereon a feedroller 102. A pressure roller 103 mounted on a lever 104; is so arrangedas to come into contact with the feed rollers at the proper time. Theabove mentioned main printing mechanism and feeding mechanism is fullydescribed and shown in the above mentioned pending application to whichreference may be had for a more detailed description. The operation ofthe machine and the relative timing of the different mechanisms will nowbe de scribed.

Let us suppose that the main printing wheels 90 have already been set totheir printing position and that a delivery slip has been inserted toextend over the main printing table 91 and also over the impressionblock and the hole 62. The main shaft 10 will rotate in the direction ofthe arrow (see Fig. 1) and the following will result. First the arm 28will raise the shaft 18 so as to lift the auxiliary printing mechanismfree from the inking pad 416. During this raising of the shaft 18 themain printing table 91 has also been raised to print the amountpreviously set up by the machine. About the same time that this printingis done the pin 76 will strike the arm 72 of the pawl 71 and willrestore the impression platen 50 if it had been accidentally orotherwise tripped before the machine had been started. Immediately afterthe shaft 18 is raised the arm 14 will vibrate to revolve the shaft 18and bring the auxiliary printing mechanism into a position as shown inFig. 3. Next the main printing table 91 will be lowered slightly and thepaper delivery slip will be fed forward by the feed roller 102. Afterthis feeding forward of the slip takes place the main printing table 91is again raised to print the amount on the slip a second time afterwhich the table 91 is lowered to its normal position. While the table 91is being raised to print the second time the shaft 18 is lowered by thearm 28 to bring the auxiliary printing mechanism against the slip toprint the word Paid and the date. It will be clearly seen that if thereis no paper over the hole 62 that the platen 50 will be released aspreviously explained. The shaft is now raised again and rotated back toits normal position after which the pin 77 will strike the arm 72 of thepawl 71 and raise the shoulder 72 to restore the impression platen 50 toits normal position. At the very last part of the revolution of theshaft 10 the shaft 18 is lowered to bring the auxiliary printingmechanism against the inking pad 46. 7
